Friedrich Berger

Alexander Dumas published The Black Tulip in 1850. The movie, Das Fest der schwarzen Tulpe, was advertised as being based upon the novel. The book's hero is Cornelius Van Baerl, and as he spends most of the novel in prison, there is very little physical action in the plot. Therefore, more action scenes and other characters were probably introduced into the film script to make it more saleable to movie audiences.
